Spider (Agelenopsis) 5. Rabbit (Oryctolagus cuniculus) ------____________________________________________________________________ Interactions and Adaptations: 1 animal & 1 plant adaptation that is used for energy · the fly uses waste from other animals for food/energy. · the plant gets water from the creek and helps the plant grow. 1 plant & 1 animal adaptation for protection or survival · the ducks is able to hold its breath underwater for a longer amount of time so it can collect bugs. · the plant has poison on it so scavengers do not eat it.
For instance, Lactobacillus acidophilus — a harmless bacterium that resides in your intestines — helps you digest food, destroys some disease-causing organisms and provides nutrients. Many disease-causing bacteria produce toxins — powerful chemicals that damage cells and make you ill. Bacteria can multiply very rapidly if given the right environment. Viruses are much smaller than cells. In fact, viruses can only be seen by electronic microscope. To reproduce, viruses invade cells in your body, hijacking the machinery that makes cells work.
Agriculturally, plants can be genetically transformed to be resistant to pesticides, spoilage, and frost. In bioremediation bacteria can be transformed to be able to digest oil from oil spills. For medicinal purposes, gene therapy is being used to help people with diseases caused by defective genes. The GFP protein is a green fluorescent protein that is the source for bioluminescent jellyfish. This protein causes the jellyfish to glow in the dark.
Fungi Fungi are skin infections caused by dermatophytes and yeasts, which are groups of fungi that are normally harmless. When these grow excessively, it causes symptoms and usually affects your skin because they live of keratin. Parasite A parasite is a life-form that survives off its host, including worms, bacteria, protozoa and amoeba. Parasites often work by stealth—you probably don’t even notice their presence. In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body.
Alpha hemolysis 3. Streptococcus pneumoniae are Gram-positive, lancet-shaped cocci (elongated cocci with a ... sensitive to bacitracin than other beta hemolytic streptococci. 4. the swelling of the capsule surrounding a microorganism after reaction with an antibody; the basis of certain tests for identifying microorganisms; "pneumococcus quellung" 5. capsules provide protection from viruses. they can be slippery to defend themselves from being eaten. Protects the bacteria from phagocytosis allowing the bacteria to stay in the body 6. pure culture 7.
Plants, animals, humans, fish, birds and reptiles can all be host to parasites. Head lice, thread and other worms are all parasites; they survive by feeding on the blood of their host. Some bacteria and viruses could be considered parasites. 1:2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacterial Infections: Salmonellas/ food poisoning, tuberculosis/TB, MRSA, coccidiosis, food poisoning, dysentery, bronchitis, ear infections, tonsillitis. Viral
In mutualism both species benefit; in commensalism one species benefits and the other is not affected; and in parasitism the parasite benefits and harms the host. 2. Prokaryotes engage in all three types of symbiosis with eukaryotes, e.g., Rhizobium is mutualistic with plants, bacteria living within the intestines and on the skin of humans are mostly commensal but some are mutualistic, e.g., anaerobic, fermenting, bacteria living within the female vagina create an acidic environment hostile to yeast and other fungi. C. Pathogenic prokaryotes cause many human diseases 1. To be pathogenic, a parasite must invade the host, resist internal defenses long enough to begin growing, then harm the host in some way.
Cane toadis known as a ground-dwelling predator where it relies on the aquatic and terrestrial insects and snails as its food. Moreover, these toads take the food left out for other pets. Cane toads are the victim of accidental movement by the pot plants or loads of timber. More important is the impact of these toads to the environment that they survive in. Cane toad protects itself through poison where it has varying degrees of poison depending on the stage of life that it is
Disease Yersinia pestis The Plague Jesus Urquijo Biology 113 Lab March 18, 2013 Microbes are what make the world what it is today. They are found in nearly every environment on earth. Each species has its own way of getting nutrients and adapting to its environment, such as pH, aerobic and anaerobic conditions, and enzymes that are essential for optimum living. The majority of bacteria living on earth are harmless if not beneficial to the human race, but those few microbes that are harmful to humans are those that cause disease. They are referred to as pathogens and need to be observed so we can prevent the spreading of disease caused by those particular microbes.
The deep volcanic ash where he found the lupine held few nutrients. But lupines, like other plants in the pea family, are able to “fix” nitrogen, thus enriching the soil. Each lupine plant created a microhabitat that was hospitable to several other plant species. Besides enriching the soil with nitrogen, the lupines also physically trapped windblown debris and attracted insects. As the insects died on or around the plant, they enriched the soil with organic matter.
